Hybrid Tea rose plant named `Olijcrem`

ABSTRACT

A new and distinct variety of Hybrid Tea rose plant is provided which forms in great abundance attractive blossoms that are orange-cream in coloration. Such blossoms are long-lasting on the plant or when cut and placed in a vase and exhibit good petal-drop characteristics. The plant exhibits an erect growth habit and forms attractive medium green foliage. Good disease resistance is provided. The new variety is particularly well suited for cut flower production under greenhouse growing conditions.

SUMMARY OF THE INVENTION

The new variety of Hybrid Tea rose plant was created by artificialpollnation wherein two parents were crossed which previously had beenstudied in the hope that they would contribute the desiredcharacteristics. The female parent (i.e., the seed parent) of the newvariety was the `Prophyta` variety (non-patented in the United States).The male parent (i.e., the pollen parent) was the `Olytel` variety (U.S.Plant Pat. No. 8,862). The parentage of the new variety can besummarized as follows:

    `Prophyta`×`Olytel`.

The seeds resulting from the above pollination were sown and smallplants were obtained which were physically and biologically differentfrom each other. Selective study resulted in the identification of asingle plant of the new variety.

It was found that the new variety of Hybrid Tea rose plant of thepresent invention possesses the following combination of characeristics:

(a) forms in great abundance attractive long-lasting blossoms that areorange-cream in coloration,

(b) exhibits an erect growth habit,

(c) forms attractive medium green and glossy foliage,

(d) exhibits good disease resistance, and

(e) is particularly well suited for cut flower production.

The new variety well meets the needs of the horticultural industry andis particularly well adapted for cut flower production under greenhousegrowning conditions.

The new variety has been found to undergo asexual propagation in Franceby a number of routes, including budding, grafting, and cuttage. Asexualpropagation by the above-mentioned techniques in France has shown thatthe characteristics of the new variety are stable and are strictlytransmissible by such asexual propagation from one generation toanother.

The new variety has been named the `Olijcrem` variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonablypossible to make the same, in a color illustration of this character,typical specimens of the plant parts of the new variety. The rose plantsof the new variety were two years of age and were observed duringNovember while budded on Rosa indica understock and growing ingreenhouses at Le Cannet des Maures, Var, France. Dimensions incentimeters are indicated at the bottom of the photograph.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The RoyalHorticultural Society (R.H.S. Colour Chart). The description is based onthe observation of three year-old plants during June while budded onRosa indica understock and growing in greenhouses at Le Cannet desMaures, Var, France. The coloration in common terms precedes referenceto the chart in some instances.
